Measuring Object Short Circuit due to Relay Contact Welding

12.2 Measuring Object Short Circuit due to Relay

Contact Welding

The SW9001 and SW9002 multiplexer modules switch a measurement signal using a mechanical

relay.

The relay contact may weld when relay switching is repeated with a large current flowing (also

when the measuring object or instrument to be connected is capacitive). When relay contact

welding occurs, the measuring object may be shorted. Periodic inspection is recommended.

Reference: "Checking for relay contact welding" (p. 26)

Example: When a battery cell is measured with the cell reversed

Selected channel

Channels not selected

Example: When each of the stacked batteries is measured
